The Someone Like You singer now joins an elite group of just four singers who have spent sixteen weeks at the top of the Billboard chart after selling 104,000 copies last week, bringing its total in the US to 6.05 million.

Whitney Houston’s Bodyguard soundtrack, Garth Brooks’ Ropin’ The Wind, Billy Ray Cyrus’ Some Gave All and the Titanic soundtrack have all achieved the record.

Adele’s feat makes it the longest stint at number one in the States by a British studio album in Billboard history beating The Beatlesâ Sgt Pepperâs Lonely Hearts Club Band and Pink Floydâs The Wall, which both spent 15 weeks at the top.

Her second album has also spent more weeks at number one that any other record since 1971 in the UK.

21 has spent 19 non-consecutive weeks at the top of the charts although it still has a long way to go until it beats current record holder, Simon and Garfunkel’s Bridge Over Troubled Water, which spent 33 weeks at number one.

Adele’s follw-up to 19 has sold over 9 million copies in the UK and US.
